Definitions

  • the present invention provides a sheet processing apparatus capable of determining whether or not a press operation is to be performed on a folded part of a sheet bundle according to the number of sheets of the sheet bundle, and provides an image forming system having the sheet processing apparatus.
  • FIG. 1 is a view schematically showing the construction of an image forming system
  • FIG. 2B is a view showing a format of sheet interval information transmitted from the finisher to the image forming apparatus
  • FIGS. 8A to 8D are views showing an example of screen transition on the operation display apparatus at the time of book-binding mode setting
  • FIG. 12 is a flowchart showing a sheet interval control process executed by the image forming apparatus
  • FIGS. 13A and 13B are a flowchart showing a sheet interval information notification process executed by the finisher
  • FIG. 16 is a flowchart showing a threshold value setting process in which a threshold value used in step S 405 of FIG. 14 is set according to sheet size and printing speed;
  • the flapper 41 in the image forming apparatus 1 is switchingly operated to temporarily guide the sheet passing through the fixing device 37 into an inversion path 42 . After the rear end of the sheet passes through the flapper 41 , the sheet is switched back and discharged from the printer 3 to the finisher 6 by the discharge roller 38 .
  • the flapper 41 in the image forming apparatus 1 is switchingly operated to guide the sheet into the inversion path 42 . Then, the sheet is conveyed to a double-sided conveyance path 43 and refed from the conveyance path 43 into between the photosensitive drum 32 and the transfer device 36 . The sheet formed at its both surfaces with images is discharged from the printer 3 to the finisher 6 .
  • the image signal controller 93 converts an analog image signal supplied from the image sensor 28 into a digital signal, performs various processing on the digital signal, and converts the processed signal into a video signal for output to the printer controller 94 .
  • the image signal controller 93 performs various processing on a digital image signal supplied from the external computer 200 via an external device I/F 97 , and converts the resultant signal into a video signal for output to the printer controller 94 .
  • the printer controller 94 controls the exposure unit 31 and the printer 3 according to the input video signal, thereby controlling image formation and sheet conveyance.
  • the finisher 6 includes conveyance roller pairs 61 a - 61 h , paths 62 a - 62 e , and changeover flappers 63 a - 63 c .
  • a sheet discharged from the image forming apparatus 1 is taken in the conveyance path 62 a by the conveyance roller pair 61 a , and a positional deviation of the sheet in a direction perpendicular to a sheet conveyance direction is corrected by a shift unit 65 .
  • the sheet is conveyed toward the changeover flapper 63 a by the conveyance roller pairs 61 b , 61 c , and conveyed by the conveyance roller pair 61 d toward the changeover flapper 63 b.
  • the conveyance roller pairs 61 g , 61 h are driven by the sheet discharge motor M 3 , whereby the sheet is guided to a processing tray 67 . Then, binding processing in which a rear end of a bundle of sheets stacked on the processing tray 67 is bound by a stapler 66 is performed, and the sheet bundle is discharged from the processing tray 67 to a stacking tray 71 a.
  • folding conveyance roller pairs 74 a , 74 b operate to discharge the sheet bundle to a book-binding tray 78 .
  • a conveyance sensor 80 b is disposed between the folding conveyance roller pairs 74 a , 74 b , a conveyance sensor 80 c is disposed downstream of the roller pairs 74 a , 74 b , and a conveyance sensor 80 d is provided in the book-binding tray 78 .
  • the flattening roller 77 c presses a folded part 300 of a sheet bundle from a direction opposite from the conveyance direction of sheet bundle, thereby flattening the folded part 300 .
  • the press roller pairs 77 a , 77 b press the folded part 300 of the sheet bundle from a direction perpendicular to a front surface of the sheet bundle, thereby strengthening the folded part 300 .
  • step S 101 the CPU 100 of the finisher 6 determines whether or not the press mode is set to “flattening” or “press,” while referring to the sheet bundle information J 3 associated with a sheet bundle of K-th copy (hereinafter, referred to as the sheet bundle K) among the number of processing copies.
  • step S 111 the CPU 100 drives the press motor M 13 to move the press unit 77 , thereby performing press processing on the sheet bundle K ( FIG. 11D ). At that time, if the press mode is set to “flattening,” flattening processing is performed to flatten the rear face of the sheet bundle by the flattening roller 77 c.
  • step S 201 the CPU 90 a of the image forming apparatus 1 controls transmission of sheet information J 1 ( FIG. 2 ) for the sheet reached and stopped at the registration roller 44 (hereinafter, referred to as the sheet N) to the finisher 6 via the communication IC (not shown).
  • step S 202 the CPU 90 a of the image forming apparatus 1 determines whether or not it receives the sheet interval information J 2 for the sheet N ( FIG. 2B ) from the finisher 6 .
  • step S 204 the CPU 90 a assigns a time stamp at that time to each of variables TP, TN on the RAM 90 c and stores values of these variables (steps S 205 and S 206 ), and determines whether or not the variable TN has a value equal to or larger than the sum of values of the variables TP, TD (step S 207 ). If the answer to step S 207 is NO, the process returns to step S 206 .
  • the sheet N is the first sheet in the job and there is no immediately preceding sheet N ⁇ 1 that precedes the sheet N, it is unnecessary to take into account a sheet interval from the preceding sheet. Thus, it is enough to wait elapse of a time (equal to variable TD) required for the finisher 6 to perform receiving preparation.
  • step S 207 If the relation of TN ⁇ TP+TD is fulfilled (YES to step S 207 ), the CPU 90 a assigns a time stamp at that time to the variable TP and stores the value of this variable (step S 208 ), and requests the printer controller 94 to restart the conveyance of the sheet N (step S 209 ). In response to this, under the control of the printer controller 94 , the conveyance of the sheet N is started by the registration roller 44 .
  • the CPU 100 determines that the book-binding process for the sheet bundle K ⁇ 1 has not been completed, obtains book-bind processing time from a book-bind processing time table TBL 1 ( FIG. 15 ) according to the sheet bundle information J 3 for the sheet bundle K ⁇ 1, and assigns and stores the obtained time to a variable TB on the RAM 102 (step S 312 ).
  • the variable TB represents a book-bind processing time (press processing time) expected to be required for the press processing of the sheet bundle K ⁇ 1, which will be book bound.
  • the table TBL 1 is prepared in advance and stored in the ROM 101 or the like.
  • FIG. 14 shows in flowchart the press mode setting process executed in step S 310 of FIG. 13B .
  • the CPU 100 sets “flattening” in the press mode in the sheet bundle information J 3 for the sheet bundle K (step S 403 ).
  • the CPU 100 sets “press” in the press mode in the sheet bundle information J 3 for the sheet bundle K (step S 404 ).
  • step S 403 After completion of the press mode setting in step S 403 , S 404 , S 406 , or S 407 , the CPU 100 proceeds the process to step S 408 where the sheet width and sheet length indicated in the sheet information J 1 for the sheet N are assigned to those in the sheet bundle information J 3 for the sheet bundle K, whereupon the press mode setting process of FIG. 14 is completed.
  • step S 305 the standard sheet interval time of 3000 msec indicated in the sheet information J 1 is set as the bundle formation time TA.
  • step S 316 the sheet interval information J 2 in which the required sheet interval time equal to 0 is indicated is transmitted to the image forming apparatus 1 .
  • step S 307 the current bundle formation time TA of 6000 msec is calculated by adding the standard sheet interval time of 3000 msec indicated in the sheet information J 1 to the preceding bundle formation time TA of 3000 msec. It is assumed here that it is determined in the press mode setting process of FIG. 14 executed in step S 310 that the folding priority mode has been set in the folding mode in the sheet information J 1 . In a case that the press mode is set to “press”, since the sheet size is A3 and the number of sheets is 2 in this example, a value of 6500 is obtained from the table TBL 1 ( FIG. 15 ) and assigned to the variable TB in step S 312 .
  • step S 503 the CPU 100 multiplies the standard sheet interval time represented by the information selected in step S 501 by a value of the variable I, thereby determining a stack processing time expected to be required to stack a sheet bundle.
  • the sheet bundle to be stacked has a sheet size corresponding to the selected information and has the number of sheets equal to I.
  • the CPU 100 obtains a press processing time (book-bind processing time) expected to be required to perform press processing on the sheet bundle. Then, the CPU 100 determines whether or not the calculated stack processing time (i.e., the product of standard sheet interval time and variable I) is shorter than the obtained press processing time.
  • step S 503 If the stack processing time is shorter than the press processing time, the productivity is lowered when press processing is performed on the sheet bundle whose number of sheets is equal to I. Accordingly, if the answer to step S 503 is YES, the CPU 100 adds a value of 1 to the variable I, thereby increasing the threshold value R compared with the number of sheets of the sheet bundle in step S 405 of FIG. 14 in order to avoid the productivity from being lowered (step S 504 ), and returns the process to step S 503 .
  • the threshold value tables TBL 2 created in the threshold value setting process of FIG. 16 can be stored in a non-volatile memory. By reading the threshold value tables TBL 2 from the memory at each subsequent start-up of the image forming system, execution of the threshold value setting process of FIG. 16 can be omitted. Instead of holding the tables TBL 1 and TBL 2 , information about the tables TBL 1 , TBL 2 can be held in the form of arithmetic formulae or the like. Instead of assigning time stamps to variables in step S 205 of FIG. 12 , etc., it is possible to use a time measured by a timer provided for each variable.
